UNITED STATES PATENT OFFICE,

JOHN L. RITTER, OF MILNES, VIRGINIA, ASSIGNOR OF ONE HALF TO JOHN P. BROWN, OF SAME PLACE.

EGG-TESTER.

SPECIFICATION forming part of Letters Patent No. 405,601, dated June 18, 1889.

Application filed October 20, 1888. Serial No. 288,706- (No model.)

To all whom it may concern:

Be it known that I, JOHN L. BITTER, a citizen of the United States, residing at Milnes, in the county of Page and State of Virginia,

have invented new and useful Improvements in Egg-Testers, of which the following is a specification.

The invention relates to ii'nprovements in egg-testers.

The object of the present invention is to improve, cheapen, and simplify the construction of eggtesters and render them more easily operated.

The invention consists in the construction and the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in. the claims hereto appended.

In the accompanying drawings, Figure 1 is a perspective view of an egg-tester constructed in accordance with this invention, one of the hinged doors being partially open to show the construction of the interior of the device. Fig. 2 is a vertical transverse sectional view parallel with the face of the egg-tester, and Fig. 3 is a section on line 00 a of Fig. 2. Fig. at is a detail perspective view of a reflector constructed slightly different from that shown in the other figures.

Referring to the accompanying drawings, A designates the rectangular frame of the egg-tester, open at the sides, and constructed of wood or some similar light material, and

' is preferably about twenty-four inches high, 35 twenty-five inches long, and thirteen inches wide, and is provided slightly below its center with a reflector constructed of metal and preferably semi-cylindrical in form; but it may be angular and corrugated, as illustrated in Fig. 3 of the drawings. By this construction the usual mirror isdispensed with, and the light of a lamp C is thrown directly upward upon the under side of an egg-tray D situated just above the reflector. The reflector is provided at the bottom with one or more transverse slots 7), that terminate in enlarged portions Z) andpermit the light, which may be an ordinary lamp 0, or a gas or an electric jet, to be placed in the middle of the reflector B.

The tray D is constructed similarly to that shown and described in my application for Letters Patent,filed August 23,1888, and serially numbered 283,540, and is placed near the top of the reflector B, and slides upon supporting- 5 5 strips E, attached to the sides of the frame, the top of which is slotted to provide an eyehole ca, by means of which the eggs F are inspected.

The frame A of the egg-tester is closed above the reflector by doors G, which are preferably metal, and are hinged by rods H, that are attached to the doors G, passing across the middle and dividing them in halves, each of which is similarly constructed and cut away at the corners to avoid the strips E, and are capable of rotation, which makes the egg-tester very easy to handle, the door being readily opened for the insertion or removal of the trays. Both sides of the doors G and the interior of the box A, above the reflector B, are blacked to prevent inside reflections. The hinged door G is held, when closed, by a spring-catch I, which consists of a piece of spring metal secured to the top of the frame A and curved around the edge and passed along the under side of the top a short distance. The spring-catch I is pro= vided just beyond the curve with a bend 2', that engages the hinged door G and holds it when closed. The top of the frame Ais pro vided 011 each side with a recess a, which permits the bend t to be pushed upward for the purpose of disengaging the door G.

From the foregoing description and the accompanying drawings the construction, operation, and advantages of the invention will readily be understood.

Having thus described the invention, I claim- 1. An egg-tester comprising the rectangular frame provided with supporting-strips adapted to receive a tray, the reflector situated beneath the supporting-strips and hav ing the transverse slot or slots, and the hinged 95 doors closing the frame above the support ingstrips, substantially as described.

2. An eggtester comprising the rectangular frame provided with an eye-hole and supporting-strips adapted to receive a tray, the I00 reflector situated beneath the supportingstrips and having the transverse slot or slots to allow the light or lights to be placed in the middle of the reflector, the hinged doors closing the frame above the reflector, and springcatches engaging the doors, substantially as described.

3. An egg-tester comprisingthe rectangular frame provided with supporting-strips adapted to receive a tray, the reflector situated beneath the supporting-strips and having the transverse, slot or slots, and the hinged doors and the spring-catches, said doors being hinged intermediate of their ends and capable of rotation to bring either end into engagement With a catch, substantially as described.

4. An egg-tester comprising the rectangular frame provided with supporting-strips adapted to receive a tray, the reflector situated beneath the supportin g-strips, the hinged doors arranged upon each side of the frame and hinged intermediate of their ends and closing the frame above the reflector, and spring-catches consisting of pieces of spring metal curved under the top of the frame and provided with bends adapted to be engaged by either end of the doors, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two Witnesses.

JOHN L. BITTER.
